Claims. (Cl. 139-390) This invention relates to an improved textile webbing having a longitudinally-successive series of pockets in longitudinally-overlapping relation.

One object of this invention is to provide an improved textile Webbing of the type set forth in ilslay Patent No. 2,358,638, granted September 19,

Another object of this invention is to provide. an improved textile webbing of the above-mentioned type in which the end walls are more securely connected to the side walls of the pockets.

Another object of this invention is to provide an improved textile webbing of the above-mentioned type which can be manufactured at a higher rate of output per loom, and at lower cost per unit of length of webbing.

With the above and other objects in view, as will appear to those skilled in the art from the present disclosure, this invention includes all features in the said disclosure which are novel over the prior art.

In the description and claims, the various parts and steps are identified by specific terms for convenience, but they are intended to be as generic in their application as the prior art will permit.

In the accompanying drawing forming part of the present disclosure, in which one way of carrying out the invention is shown for illustrative purposes:

Fig. 1 is a face view of a fragment of textile webbing made in accordance with the present invention, with a portion of the front face thereof having the weave illustrated schematically;

Fig. 2 is a longitudinal sectional view taken on line 22 of Fig. 1;

Fig. 3 is a transverse sectional view taken on line 3-3 of Fig. 1; V

Fig. 4 is a transverse sectional view taken on line i-4 of Fig. 1;

Fig. 5 is a longitudinal sectional view similar to Fig. 2 but with the float-threads cut and with the webbing opened out to more clearly show the pockets;

Fig. 6 is a longitudinal sectional view taken on line 6-6 of Fig. 2;,and

Fig. 7 is a schematic view corresponding to Fig. 2, and illustrating the manner in which certain of the warp strands extend along the webbing.

Referring to the drawing, the textile webbing [0, after having had the float-threads i I cut in a way understood by those skilled in the art of weaving, to leave short protruding end-s Na and Nb respectively attached to the side-strips l5 and I1 (Fig. 5), has a longitudinally-successive series of pockets l2 in longitudinally-overlapping relation. Each pocket l2 has two opposite side walls 13, two opposite end walls l4 and a bottom or bottom-edge l5. The respective opposite side walls I3, l3 of the pockets l2 form part of two continuous face-to-face side-strips l6 and 11.

One edge of each side-stripis secured substantially throughout its length to the adjacent edge of the other side-strip so as to form the bottom or bottom-edge 15 of each of the pockets I2. The end-walls M of the pockets extend generally parallel to one another and each has one end connected at location it to the side-strip I6 by being interwoven therewith, and has the other end similarly connected at location IE! to the side-strip [1, which location I9 is longitudinally displaced from the location 18 of the first-mentioned end, to thus produce the overlapping relation of the pockets [2.

Fig. 2 illustrates the-stage of manufacture of the textile webbing after it has been completely woven, but prior to the performing of the cutting or severing of the float-threads or strands II to produce the completed construction shown in Fig. 5. In Fig. 2, the side-strips l6 and i! are shown much further apart, and hence with the float-threads ll shown much longer, than is the actual case, in order to more clearly illustrate the fabric at this stage of its manufacture. Ordinarily, the float-threads are so short that the two side-stripstouch or almost touch.

In weaving the webbing Hi, the warp-strands or longitudinal strands include five sets of warpstrands. The warp-strands 20 form one set of warp-strands and extend throughout the width and length of the side-strip l6 and are interwoven with the weft-strands or picks 2! throughout the width and length of the side-strip IS. A second similar set of warp-strands 22 extends throughout the width and length of the other side-strip ii and is interwoven with the weft-strands or picks 2! throughout the width and length of the side-strip ll. Then there are three other sets of warp-strands respectively numbered 23, 2t and 25, and respectively schematically illustrated in the drawing, by a dot-and-dash line of one dot,

a dot-and-dash line of two dots, and a dot-anddash line of three dots, in order to makeit easy to follow the complicated courses that these strands occupy along the length of the webbing. These three sets of warp-strands 23, 2:4 and 25 are also interwoven with the weft-strands or picks 2i. By reference to Fig. 7, it will benoted that the set of warp-strands 23 represented schematically by the single-dot dot-and-clash line,

extendsfrom the extreme right of Fig. '7 as an interwoven part of the side-strip ll until it reaches the float-thread crossed-over location I la, whereupon it crosses over and is interwoven With the side-strip l6 along a length thereof until it reaches a location l8, whereupon it extends across at an angle in an end wall it until it' reaches a location H! in the side-strip I! with which it is again interwoven along a length thereof until it reaches the next float-thread crossedover location I I0. In asimilar manner, it will be observed that the set of warp strands 24, represented schematically bythe two-dot dot-anddash line, extends throughout the length of the webbing, with similar crossing over back and forth from one to the other of the side-strips l6 and I1. And, similarly, the set of warp strands 25, represented schematically by the three-dot dotand-dash line, similarly extends throughout the length of the webbing with similar crossing over back and forth from one to the other of the sidestrips I 6 and I1, all as is clearly seen in Fig. 7, with which Fig. 7, the schematic illustration of these three sets of warp strands in Figs. 1 and 6 will be seen to be in agreement.

In Fig. 7, any portions of the lines which represent warp-strands 23, 24 and 25, which are parallel to the side-strip I 6 and are nearer to the side-strip 3 than to the side-strip H, are interwoven in the side-strip l6, and similarly, portions of such lines which are parallel to the side-strip I! and are nearer to the side-strip l1 than to the side-strip l6, are interwoven in the side-strip [1.

In carrying out this weaving operation, the weft-strand, commonly known as weft-picks or weft-strands or filling-strands and designated as 2|, is interwoven With the five sets of warp strands 20, 22, 23, 24 and 25 previouslydescribed, to form the side-strips l6 and I1 and pocket-ends I4, in .a way that will be understood by those skilled in the art of weaving. Thus, the weftstrand 2! can-be passed from the bottom location l (Fig. 4) up to the top of the pocket-end member M, then back down to location l5,then up and down in the side-strip l6, then up and down in the side-strip ll, then up and down in the pocket-end l4, and so on, until a location I 8 (or I9) in one of the side-strips H6 (or IT) is reached, when the weft-strand passes up and down in one side-strip and then up and down in the other side-strip until the next pocket-end member [4 is reached for weaving. In weaving the weftstrands or picks, as the weft-strands 2| pass from one to another of the parts M, I5 and I! at the bottom-edge i5 throughout the length of the webbing, as hereinbefore described, the effect is to join the two lower edges of the strips I6 and I1 together 'to form the bottom or bottom-edge I5.

The extent or length of the woven-in length with each of the side-strips l6 and ll, of the three sets of warp strands 23, 24 .and 25 which extend along the pocket-ends M from one side-strip to the other, will be at least equalv to the distance between the anchor or connection locations of any two successive pocket-ends with a given side strip. In the particular webbing illustrated in the drawing, this woven-in length 26 is greater thanthe distance between the locations l8 (or H!) of two successive pocket-ends [4 with the side-strip I6 (or H), and will be even greater in such instances as the pocket-ends M are longer. These long woven-in areas 26 of the warp-strands 23, 24 and 25 provide such adequate anchorage for each of the opposite ends of each pocketbe understood, of course, that the weft-picks and 4 end I I, that it permits of employing less picks per unit of length, which results in less cost per unit of length of the webbin and higher lengthof-webbing output per loom employed.

Inasmuch as the Weft-picks 2! will be formed during the weaving operation at a constant number of picks per minute and as the rate of feed to the take-up roll, of the fabric being woven, is constant, when the portions 21 of the Webbing H] are being woven, more weft picks will be laid in or woven-in in these portions 21, than will be woven-in in the portions 28 of the webbing Where .a pocket-end I4 is located between the side-strips l6 and I1, and this is schematically indicated in Figs. 1 and 6 by the fact that the weft picks are shown closer together in the portions or regions than in the portions or regions 28. It will the warps are not at all located as far apart as is indicated by the schematic showing in the drawing but that ordinarily these weft and warp strands will be woven relatively close together, they being illustrated far apart in the drawing merely for clearness of the schematic illustration.

At the upper parts of Figs. 1 and 6, the three warp-strands 23a, 24a and 25a, respectively each form one of the three said sets 23, 24 and 25 of warp-strands which cross along the pocket-ends M as hereinbefore described. Each of these three warp strands 23a, 24a, and 25a is of opticallydistinctive appearanceboth from the remainder of its said set of warp-strands and from each of the other two of such optically-distinctive-appearing warp-strands. In one form of construction according to the present invention, each of the warp-strands23a, 24a and 25a is formed of a strand of a'color which is "different from the other warp-strands of its group, these three strands being black, for example, whereas the remainder of the warp-strands are white. And although the warp-strands 23a, 24a and 25a are all of the same colon namely, black, inasmuch as they are at different locations transversely and in the general plane of the webbing, from each of the other two they serve to optically indicate the general location of the crossover 'or fioat-thread locations l I, thus aiding in the ready cutting of the float-threads II when this is to be done to complete the formation of the webbing. It will be appreciated that instead of having the strands 23a, 24a and 2541 all of the same color, such as black, each could be of a diilerentcolor from the other, and in such instance, it would not be necessary to have them at different locations transversely of the webbing in order to optically indicate the location of the float-thread crossovers II. It will also be apreciated that instead of relying on difierent colors to produce the distinctive appearance, such distinctive appearance could be obtained either by having each one of an optically-distinctive weave or of an optically-distinctive difierent material.

Although the warp-strands 23a, 24a and 25a extend along the webbing I 0 at actual different locations transversely of the webbing, as previously stated, the showing of the other, warp-strands 23, 24 and 25 at locations displaced transversely of the webbing is purely schematic to enable the eye to easily trace the lines on the drawing which schematically represent these warp-strands, and the particular location transversely of the fabric, of any one of these lines relatively to any other one of these lines has no significance whatever.

The invention maybe carried out in otherspe-.. cific ys than those herein set forth without gnomes departing from the spirit and essential cha'racteristics of the invention, and the present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive; and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
